COPYING-PRESS.

SPECIFICATION forming part of Letters Patent No. 339,878, dated April 13. 1886.

Application filed January 15, 1886. Serial No. 188,651.

To all whom it may concern.-

Be it known that I, EDWARD MoR'rrirEE HAINES, of Dayton, in the county of Montgomery and State of Ohio, have invented a new and useful Improvement in Copying- Presses, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which- Figure 1 is a perspective view of my improved copying-press, showing the copy-book unrolled. Fig. 2 is a transverse section showing the copy-book rolled. Fig. 3 is a detail view of the binding of the hook. Fig. 4. is a longitudinal vertical sectional view of part of the cylinder, showing the crease, hem, and ends of the elastic bands.

Similar letters of reference indicate corresponding parts in the different figures of the drawings.

The object of my invention is to provide a simple, inexpensive, and portable press for copying letters.

My invention consists of a hollow split cylinder formed of spring material, a copyingbook having a back adapted to be received in the slot of the cylinder, and elastic bands ap plied to the outside of the book when rolled on the cylinder to retain the book under pressure during the process of copying.

The cylinderAis formed of sheet metal, and is slotted throughout its entire length in one side thereof to receive the back of the copyhook B. The material of which the cylinder A is made is sufficiently elastic to cause the cylinder to regain its normal shape after it is relieved from pressure. The cylinder is formed of sheet steel, elastic sheet-iron, brass, or other springy material, and the adjacent edges are returned upon themselves upon the inner side of the c linder as shown in Fi 2 to irovide rounded edges for receiving the sides of the book. The sheet metal at the ends of the cylinder is hemmed, and creases are formed near the ends for receiving the elastic hands a, which retain the back of the book in its place in the slot of the cylinder. The book B is formed of a series of leaves folded around a triangular rod, 1), of wood or other rigid material, and stitched along the back, so as to inclose the wood, as shown in Fig. 3. The book is provided with a covering, 0, of oil- (No model.)

cloth or other suitable material, which extends beyond the frce edges of the leaves of the book on one side thereof, so that as the book is wrapped around the cylinder the longer side of the cover will cover the edges of the leaves. The leaves forming the body of the book are made of tissue-paper, such as is usually employed in letter-copying b0oks,and the leaves are prepared for receiving the copy of the letter by moistening them in any convenient way, but preferably by applying to the leaf a cloth, 0, containing sufficient water to moisten the leaf.

The manner of producing a copy in my improved press is as follows: The letter to be copied is placed in the book and the leaf on which the copy is to be made is spread over the letter, and uponthe back of the leaf is laid a moist cloth, 6, when the book is closed and rolled tightly around the split cylinder A, so as to contract the cylinder in the operation of rolling. After the book is rolled closely around the cylinder two or three strong elastic bands, (I, are stretched over the book, holding it tightly around the split cylinder A, and the cylinder, by its elasticity, expands, thus main taining between the cylinder and the elastic bands a constant pressure upon the book and its contents. After the letter has been held for two or three minutes in contact with the leaf of the book the elastic bands (1 may be removed and the book may be unrolled, when the letter from which the copy is made and the moist cloth (2 will be removed.

To prevent blurring the copy sheets of ordinary newspaper are inserted in the book on opposite sides of the leaf bearing the copy.

The book '3 may be allowed to remain in its position in the slot of the cylinder A until filled, when it may be removed by taking olf one of the elastic hands a and replaced by a h Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. The combination, in a copying-press, of the split spring-cylinder A and the copyingbook B, the said cylinder being arranged to press outwardly against the book rolled upon it, substantially as herein shown and described.

2. In a copying-press, the combination of the split spring-cylinder A, the copying-book B, and the elastic bands (0, substantially as herein shown and described.

3. In a copying'press, the combination of the split spring-cylinder A, the book B, and the elastic bands d, as herein shown and described.

4. In a copying-press, the combination of the split spring-cylinder A, the book B, having in the back thereof a rod, 1), and means,

substantially as described, for pressingthe-go book upon thecylinder A, as herein specified.

5. In a copying-press, thecombination o f the split spring-cylinder A, having grooves near the ends thereof, "the elastic bands a,and

the book B, substantially as herein shown and 25 described.

6. In a copying-press, the combination of the split spring-cylinder A, having grooves around the ends thereof, the elastic hands a,

the book B, having the rod bin the back 30.
